Martin Luther King Jr. was more radical and angry in 1960 than in 1955, more of both in 1965 than in 1960, and more of both in 1968 than ever. The great demonstrations in Birmingham, St. Augustine, and Selma yielded the civil rights bills, but King struggled to adjust to the rise of Black Power and dared to oppose the Vietnam War, burning his alliance with President Johnson. King provided the theology of social justice that the civil rights movement spoke and sang.
